81.176Rounding 81.1763 to three decimals, look at the digit just to the right of 6.Since the digit is less than 5, do not change the rounding digit which is 6, but drop all digits to the right of it, thus drop 3. Therefore, the answer is 81.176But just in case that digit is greater than or equal to five, add one to the rounding digit and drop all digits to the right of it.Example: round 81.1765 to three decimals, the answer is 81.177.
In comparing decimals, the key is to look at the place value of each digit. In this case, 0.59 is less than 5.09 because the digit in the tenths place (0.5) is smaller than the digit in the units place (5). Additionally, when comparing decimals, you can also align the decimals and compare digit by digit from left to right. In this case, when aligned, 5.09 is greater than 0.59 because 5 is greater than 0.
Pi is not a digit because it has decimals. I believe a digit is a round digit meaning a whole number and no decimals.

Write them as decimals, and compare. If the first digit of two numbers is equal, compare the second digit; if the second digit is equal, compare the third digit, etc.
